This hadith is about the etiquette of sneezing in Islam. It was narrated by Abu Ayyub that the Messenger of Allah said when one of you sneezes, they should say “Al-Hamdulillahi 'Ala Kulli Hal” which means “All praise is due to Allah in every circumstance”. The person replying to them should then say “Yarhamukallah” which means “May Allah have mercy upon you”. Finally, they should also say “Yahdikumullah Wa Yuslihu Balakum” which means “May Allah guide you and rectify your affairs”. This hadith teaches us that we must be polite and courteous when responding to someone who has just sneezed. We must remember to thank God for all circumstances no matter how small or insignificant it may seem at first glance. We must also wish mercy upon those who have just sneezed as well as ask God for guidance and success for them in their lives.
